Gabbro
Identifier
NAO-15
Description
Gabbro with hydrothermal "oceanic" processes and prehnite-pumpellyite metamorphic overprint.
Plagioclase, clinopyroxene, olivine, ilmenite. metamorphic paragenesis: albite, sericite, chlorite, hematite, sphene, carbonates. Well-preserved relics of pyroxene, sometimes with traces of recrystallization in "oceanic" conditions of high temp. Plagioclase nearly complete saussuritized, only rarely with preserved relics; olivine substituted by chlorite, hematire, carbonates.
